Abstract
OBJECTIVE:Photobiomodulation (PBM) therapy has proved to be effective for a wide range of oral pathologies including oral dryness, but the literature still lacks reports of clinical trials and protocols. The purpose of our study was to evaluate the effects of different wavelengths of PBM on salivation in patients suffering from hyposalivation aiming at determination of optimal treatment protocol. MATERIALS AND METHODS: This study included 30 patients whose major salivary glands were treated with low-intensity diode laser BTL2000 (Medical Technologies, s.r.o., Czech Republic) during 10 consecutive days. Patients were randomly assigned into two groups, each of 15 patients, and treated with PBM of 830 nm and PBM of 685 nm, respectively. The whole unstimulated and stimulated saliva quantities were measured each day during 10 days, before and after laser treatment, and at 10th day after treatment was ended. RESULTS: Results have shown that the laser treatment significantly improves salivation (p < 0.0001) in both groups after 10 days treatment. The salivation also remains improved 10 days after the end of treatment. The patients treated with PBM of 830 nm have had continuously higher values of quantity of saliva. CONCLUSIONS: Our results have shown that both laser wavelengths were effective in increasing salivary flow rate, and the improvement in salivation was statistically significant. The effect of treatment could be observed 10 days after the completion of treatment, thus providing evidence not only of stimulative effect but also indicating regenerative potential of PBM therapy.
